HRMAN F. SCI-IBODER, 0F BERWYN, ILLINOIS, ASSIGNOR TO WILLIAM I-I. IVIINER, OF CHICAGO, ILLINOIS.

JoURNAL-BEARING MOLD.

Specification of Letters Patent.

Application filed July 3, 1909. Serial No. 505,839.

To all 'whom it may concern:

Be it known that I, HERMAN F. SCHRODER, a citizen of the United States, residing in Berwyn, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Journal-Bearing Molds, of which the following is a speciication.

My invention relates to improvements in molds for manufacturing soft bearing-metal liners or shells for journal bearings for cars and other aXles.

The object of my invention is to provide a journal bearing mold suitable for manufacturing the soft bearing metal shells or liners of the journal bearing forming the subject of my pending application, Serial No. 474,070, filed Jan. 25, 1909, or of the Muhlfeld Patent No. 904,634, and by means of which such soft metal bearing shells or liners may be rapidly and cheaply cast and readily removed from the mold without injury thereto.

My invention consists in combination with the opening and closing members of the mold, preferably hinged together and comprising a main or stationary member and a hinged or door member and movable core members for forming the tapering lubricant cavities in the liner or bearing shell cast therein, of connecting means between the Yhinged member or door of the mold and the movable core members thereof to automatically operate the movable core members to eject the soft metal bearing shell or liner from the mold by the opening of the door.

It further consists in connection with the main and door members of the mold, of a rocking lock shaft on one of the members furnished with eccentric slotted locking rims and coperating adjustable locking rollers on the other member adapted to enter and engage t-he slotted locking rims of the rock shaft on the first member to enable the two members of the mold to `be snugly, firmly and securely locked together and readily opened and closed.

It further consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described.

In the accompanying drawing forming a part of this specification, Figure 1 is a plan view of a journal bearing mold embodying my invention. Fig. 2 is a horizontal section on line 2-2 of Fig. 3, showing certain parts in elevation, and the locking devices on the main and door members of the mold in position for opening the mold. Fig. 3 is a central, vertical longitudinal section. Fig. 4 is a side elevation. Fig. 5 is a front elevation showing the door of the mold open. Fig. 6 is a side elevation showing the mold with the door open and Fig. 7 is a rear elevation.

In the drawing, 1 is the main or stationary member of the mold and 2 the door or hinged member thereof, the two members being hinged together by a pin 3 extending through suitable ears or lugs 4, 5 on the two members of the mold. The movable or door member 2 is provided with a handle 43 for swinging it horizontally open and closed.

The main or stationary member 1 of the mold is preferably water jacketed or provided with a water chamber 6 connecting with the inlet and outlet pipes 7, S through which water may circulate to cool the mold' and facilitate the casting operation.

The mold members l, 2 are furnished with an upright gate 9 having a plurality of runners 10, 10, 11 at different heights communieating with the interior of the mold, the upper two of which, 10, 10, are preferably upwardly inclined or deflected to give the inflowing molten metal a somewhat upward deflection or direction, as this I find aids in producing solid, perfect and homogeneous liners or castings. The vent 12 at the upper end of the mold is preferably formed in the door or hinged member 2 at its meeting face with the main member and provided with the customary telltale or enlargement 13.

The member of the mold which forms the ribs or thickened portions 14 on the upper face of the soft metal liner or bearing shell 15 is preferably the main or stationary member l, and it is provided with movable core members 16 which form the flaring lubricant cavities 17 in the soft metal bearing shellor liner 15. The movable core members 16 are pointed or taperinor in shape and each have a round cylindrica stem or shank 18 adapted to slide in and project through suitable sockets 19 in the mold member 1. The shank or stem 18 is preferably larger than the core member 16 at the base or outer Aend thereof to form shoulders 20 which serve t'o give a more extended bearing or engagement against the soft metal liner 15 when the core member is reciprocated to eject the liner or casting from the mold. The stems or Shanks Patented Nov. 1, 1910.

of the core members are furnished with slots 21 to receive a connecting bar 22 to which the same are connected by pins 23, the core sockets 19 on the main mold member 1 being also furnished with slots 24 to accommodate said connecting bar. rlhe movable cores which also serve as ejectors to force the soft metal liner 15 or the casting formed in the mold out of the same, are simultaneously andrautomatically operated through and by the door or hinge member of the mold as it is swung open through suitable connecting mechanism, consisting preferably of a lug or arm 25 on the door or hinge member 2 of the mold near the hinge axis thereof which engages a piston or pin 26 mounted in a suitable bearing 27 on the main member of the mold and'connected to or engaging a forked lever 28 pivoted to suitable lugs 29 on the main member of the mold by a pin 30, and which forked lever fits in suitable slots or openings 31 in the upright connecting bar 22 of the core members or ejector devices 16. The piston 26 is preferably connected to the fork end of the lever by a pin 32. The movable cores 16 are restored to position by engagement with the door of the mold when it is again closed.

The two members of the mold are securely locked in their closed position by means of a rocking lock shaft 33 having a lever 34 for turning it and mounted in suitable bearings 35 on the main or stationary mold member 1, and provided at its upper and lower ends with eccentric locking rims 3G having lateral or radial slots therein to receive the coperating locking rollers 44 on the door member of the mold, and which are journaled upon upright pins 37 and adjustably secured by right angle screw threaded stems or bolts 38, preferably integral with the roller pins, to the door member; the locking rollers being accurately adjustable in position by nuts 39, 40 on the stems or bolts 3 The rocking lock shaft and the mold member upon which it is mounted are preferably furnished with stops 41, 42 to limit its turning movement, and thus insure proper registry of the slots in its locking rims with the locking rollers on the door preparatory to swinging the door open or shut. The stop 41 is preferably a pin or projection on the rocking lock shaft 33, and the coperating stop 42 may preferably be the adjacent upright face of the mold member 1 which is adapted to engage the stop 41 from the shaft 33, and thus limit its turning movement, as will be readily understood from Fig. 2 of the drawing. The main and door members of the mold are preferably furnished with an intertting rib and groove at their front ends to insure tight closure.

While my journal bearing mold is specially intended and designed for making soft metal liners or shells for journal bearings, it may of course be used for' .inaking' other articles.
